Vitthal Mendapra, president, Bhavnagar Diamond Association (BDA) told TOI, "Bhavnagar is the trading centre for polished diamonds. We are trying to find out the links for synthetic diamonds, which has earned a bad name to Indian diamond industry."

In the wake of the rising issue of natural diamonds and synthetic diamonds being mixed and the non-disclosure of the same, The Surat Diamond Association and the Gems and Jewellery Export Promotion Council organised a seminar.

Advanced cutting tools are one of the important factors to improve production efficiency of the manufacturing industry. Statistics indicate that advanced cutting tools can improve production efficiency substantially.

Statistics show that from the first half of last May to the present, China's sales revenue of natural diamond has hit ￥1,000,000,000, among which consumption of 2 carat and five carat diamond has risen by more than 40%.

Recently, Xiao Dongshan, academician of the Connecticut Branch of the U.S, Academy of Engineering will cooperate with a company in Hunan Province to tackle the problems in nano-crystalline cemented carbide technology.

Purdue University in the U.S. released a research that attaches nano diamond with nitrogen-vacancy center to metamaterials made of TiN and AlxSc1-xN , and pumps by laser so as to enhance single photon emission of metamaterials.

In 2015, Fangcheng County depends on industrial agglomeration and superhard materials industrial park to develop five major industries - mechanized equipment, superhard materials, new energy, minerals and building materials, and agricultural products.

PCBN (Polycrystalline Cubic Boron Nitride) is the hardest substance that is second to diamond. Traditional processing techniques are difficult to deal with PCBN. A recent research designed a LBM (Laser Beam Machining) technique to deal with PCBN.

A team of researchers from Euclid TechLabs and Argonne National Laboratory's Center for Nanoscale Materials have demonstrated a plug-and-play solution capable of operating in this high-electric-field environment with a high-quality electron beam.

Purdue University in the U.S has recently published an research on Nature claiming that they have developed a new technology called confined-pulse laser deposition that can produce synthetic nano diamond on the graphite's surface.

Scholars of Novosibirsk have recently invented a unique superhard material with special structure natural diamond. The new invention of the specialists has increased the service life of cutting tools and drilling tools.

Registered in Luxembourg, the synthetic diamond material company—Element Six (a subsidiary of the De Beers), has recently announced the development of a new thermal grade of diamond grown by chemical vapor deposition (CVD).

Recently, British scientists have developed a new microscope technology that can be used in observing the nano diamond in living cells. The technology is of great significance to medical research and clinic treatment.

With the effort of Japan Sumitomo and the Element Six, the Method of high temperature and high pressure to produce synthetic monocrystalline diamond has gradually replaced natural diamond in various application fields since 1990.

According to TASS, the Ministry of Finance of Russia revealed that Russia has exported 1,979 carat of diamond in the first half of 2014. The total value was ＄25 billion, which increased 8% compared with the same period last year.
